The Toyota FCV, or Fuel Cell Vehicle, is a hydrogen-based concept car that’s set to appear in California (where hydrogen refueling stations already exist) in 2015. With an electric motor in the front and hydrogen tank in the back, the car is designed to take in oxygen through the front. It then combines that oxygen with hydrogen to produce fuel in the fuel tank, and emits water vapor as exhaust. It has a 300-mile range and can recharge in three to five minutes.
